Opis:: This article is devoted to the functional analysis of the external respiration apparatus of students of different sports specializations. It examines the level of functional reserves of external respiration apparatus according to indices of power, mobilization and economical efficiency of male football players and athletes – above average ─ and of female football players and athletes – average. The assessment of the reserve capacity of external respiration apparatus may be used in the construction of the training process and will assist in the professional selection and sports orientation of students of the faculty of physical education.

Opis:: Renewable energies especially Run-Of the-River (ROR) power plants are increasingly used for the electricity generation in the power systems. The uncertain and intermittent nature of these plants arisen from variability of water flow, however, has led to some problems in their integration to power systems. Thus, the operating reserve requirement in a power system containing large ROR plants is a main challenge, which has to be addressed properly. In this way, this paper presents an analytical approach to determine the adequate spinning reserve based on the well-being approach during the system operation. The reliability model based on the components failures and uncertainty nature of water flow is introduced for ROR plants operation studies. This approach not only evaluates the interaction between these energies and conventional units, but also determines the contribution that ROR power plants can make in load carrying capability of a power generating system. Two reliability test systems, utilized from water flow data of Sheshpir River in Iran, are examined to demonstrate the effectiveness of the proposed model.
